Hey everyone,

I am looking to purchase some BBS CI-R rims for my 2018 C43 and have been getting a lot of mixed information from dealers. Some say they won't fit, another one said they will with a $300+ install kit and another wasn't sure (email from them)

"...I’m not too sure if the front 225 tires will fit the 8.5” perfectly or it will be a bit stretched. I’d consult with Mercedes on the offset though, since the 19x8.5 is 45mm offset and the 19x9 is 42mm offset"

Currently have:

225/40R19 on the front
255/35R/19 on rear

Do any of you know the offset numbers that will work?

Thank you for any information you guys can share.

I did...that was the thread that made me sign up here and ask. Reading through it, there were many conflicting posts and different answers.

No more conflicting answers if you read through it. This is the general consensus:

8.5J 30ET front
9.5J 40ET rear

225 40 19 will work on 8.5J
255 35 19 will work on 9.5J

If you get the above rim spec, you can upsize to 235 and 265 respectively as well.

This fitment should be very good.

^ I thought the rear offset for flush fitment is around +50?

munis

Nah I am at 46 and I can still use a 10mm spacer in the rear.

There is more than enough information in that thread to answer your vague question or at least for you to pose a more constructive question.

BBS offer a built in spacer that is very convenient to change the effective offset. I would never pay $300 for it.

There are so many recommendations for good fitment in that thread, if you don't understand fitment, in general, that's another story.

HI,

I would also like to ask somethig..

I want to mount 255 front and 285 rear tires.
What offet do I need?

255 front's will make the car look like an ATV.

245 in front... I dont think that 255 would make such a difference to look like ATV

to ensure you have good inner clearance you'd have to offset the wheel even further out and the wider front tire will be a lot more square. To fit a 255 in the front while still being in check will require a lot of modification and playing with camber settings and more, maybe even pulling the fenders a bit.

running a 255 upfront, that is not mexiflush, is not plug and play on this car and nobody has done it properly under the OEM fenders.

245 is then max i can use without modifications?

Sorry to be updating this old thread, but after searching and reading, I'm still none the wiser. Seems like lots of contrasting opinions and views.

I too am looking to fit some new BBS CI-R wheels on my 2018 plate C43 saloon.

I don't care about the tires as I'll be buying an entirely new set, but can someone recommend me the best 19" wheel sizes to get in order to keep things as simple and as flush as possible for both front and rear, ideally without the need for much or any additional work, spacers, fixtures or time. I will be keeping suspension etc stock.

I'm thinking I need the following:

Front:

2x BBS CI-R - 8x19 ET44 5x112 82
2x Michelin Pilot Sport 4S 235/40 (or 35) ZR19 96Y

Rear:

2x BBS CI-R - 9x19 ET42 5x112 82
2x Michelin Pilot Sport 4S 255/35 ZR19 96Y

Or one of the following

2x BBS CI-R - 8.5x19 ET32 5x112 82
2x BBS CI-R - 8.5x19 ET45 5x112 82

Appreciate any advice.

Check the other thread on wheel fitment, you’ll find your answers there.

Hi,

I've already checked the other thread. There's lots of conflicting opinions on the offset and on wheel width etc, hence asking in this thread for clarification.

TModelle

I think it’s pretty clear, hardly conflicting at all, just need to read it through properly, you’ll find your answers there.

Nib95

It's not really clear at all, at least not to people who are new to this sort of thing, hence the OP didn't understand either since several people in that thread and this one have been recommending different sizes etc.

My clarification was on which set up would require the least amount of effort and change, whereas some appear to be going wider than perhaps ideal etc.

Star4life

something to consider as well. fitment heavily depends on ride height,are you lowered? as well as personal preference and individual vehicle tolerances. some people like more aggressive so some will say a lower et looks better while others, like myself, prefer a more conservative fitment. the thread should give you a rough idea of where to start and you can dial in from there.

there really isn't. there's a very small tolerance of what works up front that is pretty well established.

any debate going on there is about the outer limits which should not concern you if you can't make heads and tails of fitment.

here. or run stock tire sizes

Nib95

Thanks Alexasa. Someone in the other thread mentioned that 8.5 might be cutting it a bit fine for the front (on stock suspension). Out of curiosity what makes you pick 8.5 over 8?

Kindest regards

TModelle

Due to the tyre size.

A 235 will fit on an 8 inch rim
